-Subject: [PATCH] fix build with --disable-threads
-
-SDL_LinuxSetThreadPriority() has been added since version 2.0.9 and
-https://github.com/SDL-mirror/SDL/commit/f25a7fa870bdceb339e5105973f689606bcb9086
-
-However, this function is used in src/dynapi/SDL_dynapi_procs.h even
-when SDL_THREADS_DISABLED
-
-However, when SDL_THREADS_DISABLED is set, SDL_LinuxSetThreadPriority is
-not defined because thread/pthread/SDL_systhread.c is not built
-
-So check SDL_THREADS_DISABLED in addition to __LINUX__
-
-Fixes:
